NF Network Function NFVI NFV InfrastructureVNFC Virtualized Network Function Component VR Virtualized Resource 4 Concepts and background 4.1 Overview The evaluation of PLMN-system behaviour will require performance data collected and recorded by VNF(
41、s) according to a schedule established by the EM 2. However, not all of these measurements will be required all the time, or from every VNF. Therefore, it is necessary to administer the measurements so as to determine which measurement types, on which measured resources, at which times, are to be ex
42、ecuted (see TS 32.401 2). The essence of NFV is to migrate the execution of network functions from vertically integrated hardware to the industry standard COTS (commercial of-the-shelf) servers in the data centre. Performance measurements that are independent of the migration (e.g. handover, trackin
43、g area update related measurements 7) are not impacted. Therefore, these performance measurements can be reused. Other performance measurement that are to measure the hardware usages (e.g. MME Processor usage 7) are impacted by the Virtualized Resource (VR) performance measurements. 4.2 Performance
44、measurement data collection methods Figure 4.2-1 shows the PM data collection methods for virtualized networks. When it is necessary to collect the PM data (i.e. PM data related to 3GPP Network Function and 3GPP NF PM data related to VR), NM needs to create a PM collection task at EM. So EM knows th
45、e measurement types, the measured resources, the recording periods and collection times wanted (see TS 32.401 2). For PM data related to 3GPP Network Function collection, EM will request VNF(s) to collect the PM data related to 3GPP Network Function as specified by NM. For VNF PM data related to VR
46、collection, EM will create a PM collection task at VNFM to collect VNF/VNFC PM data related to VR, based on the information provided by NM, so VNFM knows the measurement types, the measured resources, the recording periods, and collection times wanted. Then, VNFM will create a PM collection task at
47、VIM, based on the information provided by EM (see clause 7.7.2 8). VIM will request NFVI to collect the VR PM data as specified by VNFM. The various PM data collected are stored in data repositories. Data stored in data repositories may be fetched by NM (or any authorized user). ETSI ETSI TS 128 520
